Can I "borrow" rocker arms from my '65 273 for my '71 340?

I have my original 273 rocker arms on my current 340. I had the pushrods made custom back in 1992 for using a hydraulic cam in my 273. I have since used the same push rods and rockers on 2 other 340s. The fit into each engine without issue. Not saying other people have not had issues. I don't think Chrysler made a whole bunch different standard pushrods for other engines to work with non adjustable. My 273 shaft have the banana grooves in the bottom.
